(91133) 1998 HK151, also written as 1998 HK151 is a plutino, so it has a 2:3 resonance with Neptune, simalar to Pluto. It is in an eccentric orbit which has a perihelion (closest approach to the Sun) at 30.388 AU and an aphelion (farthest approach from Sun) at 48.996 AU. It is 133 km in diameter, so it is unlikely to be classified as a dwarf planet due to its relatively small size. It was discovered on April 28, 1998 at the Mauna Kea Observatory, Hawaii.
